Suppose that the air resistance a car encounters is independent of its speed. When the car travels at 15 m/s, its engine delivers 20 hp to its wheels. What is the power delivered to the wheels when the car travels at 30 m/s

22.5 hp

Explanation:

The power delivered to an object is given by :

Where

F is force and v is velocity of the car.

For the same force, power is directly proportional to the velocity.

So,

So, the new power is 22.5 hp.

the temperature and the pressure affect solubility. temperature affects by changing the properties of the solvent. the increase in pressure increases solubility, the decrease in pressure decreases solubility.

cant without the picture! ?
